M. Koh et al., DEVELOPMENT OF THE SINGLE-ION BEAM-INDUCED CHARGE (SIBIC) IMAGING TECHNIQUE USING THE SINGLE-ION MICROPROBE SYSTEM, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 93(1), 1994, pp. 82-86
In order to minimize image degradation of IBIC (ion beam induced charg
e) during observation, the single ion beam induced charge (SIBIC) imag
ing technique has been developed by using a single ion microprobe, whi
ch enables us to hit a particular site of a device with single ions on
e by one. With only five He single ions per pixel, we have succeeded i
n obtaining reasonable quality images of an active area of a device. S
ince the number of defects induced by five single ions is quite low, t
he irradiated device was still alive for subsequent process and device
diagnoses.
